I applied through a recruiter. I interviewed at Oracle (Seattle, WA)
Interview
Fairly easy tech screen. Loop was a bit of a mess. Coding portions required AI which was not mentioned ahead of time. One of the interviewers told me to find bugs in some code using AI, but accidentally pasted the solution instead of the buggy code which led to issues.
I applied through an employee referral. I interviewed at Oracle (Nashville, TN)
Interview
Standard coding screen followed by loop rounds.
Loop rounds -
1. System design - focused on the infra aspect more
2. Behavioral - turned into technical quickly and did some white boarding to explain how I cracked a problem.
3. Bartender - as they are all from platform team, most of their questions were targeted for infra position and that confused me.
Bias for action seemed very important for them than any other principle.
Coding - another leetcode medium and was easy to solve.

Question 1
System design - Youtube using barebones infra instead of ootb services
The interviews were mostly medium level leetcode questions. Takes a lot longer than you would expect. About 3 months from beginning to end. The offer stage and background stage take the longest
